TEST PROCEDURE 002

STANDARD COMPONENTS

1. General

This procedure provides guidelines for aiding the inspection team in quickly obtaining an overall assessment of the

readiness of standard components following periods of depot storage. Standard components include:

Discrete Semiconductors

Resistors

Capacitors

Inductive Devices

Relays and Solenoids

Switches

Connectors

Cabinets, Chassis, Relay Racks, etc.

This procedure is intended to be used only as a guide in performing the component inspections; the inspections should

incorporate other known defects from actual experience with components under storage conditions.

2. Visual Inspection

Visual inspections shall be performed to identify any evidence of damage, corrosion or contamination which will interfere

with the normal application of the components. Included shall be checks for the following defects as they apply to the

specific components under inspection:

(1) Corrosive wear, moisture, or formation of contaminant films on contacts

surfaces

(2) Brittleness (or shrinking), swelling, or rupturing of plastic encap-

sulants (microelectronics, semiconductors) or of plastic parts, used

in motors, relays, and solenoids

(3) Evidence of seal leakage

(5) Fungus growth, moisture, dust, and insects in cabinets, chassis, and

relay racks

(6) Evidence of component moisture permeation

(7) Cumulative dust, dirt, and sand particulate damage

(8) Components, damaged from depot handling.

Each defect found shall be considered as major.

3. Parametric Inspection

Microelectronic devices, discrete semiconductors, and other special components shall be functionally tested to assure

operability using readily available test equipment. The inspections shall include the testing of only common parameters

and, in the case of microelectronic devices, the exercising of key functions at practical operating speeds. These

parameters and key functions shall be determined from a review of the component specifications and manufacturing

ratings in view of the equipment and facilities that are available for in storage inspection.
